FWIW, it looks sane to me to do so, ServiceMain declaration is in
charge to start the service, and to wait for the postmaster to stop,
and indeed process may increment dwcheckpoint in -w mode, and it
expects for process to wait for 12 times but this promise is broken.
The extra calls to SetServiceStatus are also welcome to let the SCM
know the current status in more details.

A back-patch would be good as well...
